Several powerful storms unleashed a myriad of weather phenomena across the United States this week.

A large storm system initiated a rare and historic tornado outbreak across the Plains. According to the National Weather Service's Storm Prediction Center (SPC), there were 47 reports of tornadoes on Monday. In addition, there were over 100,000 lightning strikes from Monday night into Tuesday.

"This event was larger than anything seen so late [in the year] so far west in the Central U.S., " said Mike Smith, senior vice president of AccuWeather Enterprise Solutions.

"Looking at all Novembers since 1950, this was an extremely atypical event for the month when it came to location," Smith said.

Nine tornadoes were reported in Kansas, with an EF-3 tornado tracking 51 miles from Kismet to Ensign, Kansas. No injuries were reported but there was damage to buildings and power lines.

Two tornadoes impacted the city of Pampa, Texas, where the National Weather Service confirmed one EF-3 tornado and one EF-1 tornado.

The back end of the system that caused the influx of tornadoes was responsible for blizzard conditions across parts of Colorado and Kansas. Flights were delayed at Denver International Airport and portions of Interstate 70 were closed due to the storm.

A snow emergency was declared in Colby, Kansas, after more than a foot of snow was measured on Tuesday. First responders were called to rescue stranded motorists.

Kansas Gov. Sam Brownback issued a state declaration of emergency for the areas affected by the storm.

While the central U.S. was facing severe storms and a blizzard, a separate storm system slammed the Northwest.

Along with damaging winds, flooding rains and mountain snow impacted British Columbia, Washington and Oregon through Tuesday night. At least three people were killed in Washington as a result of the storm.

Washington Gov. Jay Inslee declared a state of emergency Wednesday as a result of the storm.

At the height of the storm, over 300,000 were without power. The NWS office in Spokane, Washington, said utilities reported more power outages than the ice storm from 1996 that killed four people and cost the city $22 million.

Winds gusted up to 71 mph in Spokane on Tuesday afternoon, while a 137-mph gust was measured at the Mission Ridge Ski area in Chelan County, Washington.

Widespread wind damage was also reported in the United Kingdom this week as a result of Storm Barney, the second Met office-named storm of the season. Winds were widespread in the range of 70-80 mph (113-129 km/h). A peak gust of 85 mph (137 km/h) was reported in Gwynedd.

Barney left thousands without power from Tuesday night into Wednesday across Wales, the Midlands and in southern and eastern England, while also causing disruptions to rail and ferry service.

In-fa became the 27th tropical cyclone of the year in the west Pacific and strengthened into a typhoon at midweek.

Earlier this week, In-fa brought gusty winds and heavy rain to Chuuk. The storm also brought more than 325 mm (13 inches) to Nukuoro Atoll in only 24 hours.
